Hi, my dell laptop won't boot. no beep codes, and I have 2 different LED POST codes
When charger is plugged in the code is
ON-FLASH-ON or SOLID-BLINKING-SOLID
When charger is unplugged, battery only:
ON-FLASH-FLASH or SOLID-BLINKING-BLINKING (the blinks are not the same time, they alternate)
And after some time of trying, the laptop will boot but error will be shown which is this
if I run the diagnostics, result will show that memory is okay, but it will fail the test when it is testing the hard drive.
Is this a motherboard problem? I tried re-seating the RAM but same problem with occur.
